Simulated large aperture lens

摘要

A camera apparatus includes a photogrammetric range sensor, small aperture lens and a processor configured to carry out a method for simulating a large aperture lens. The method includes capturing a photographic image data of a scene using the camera with the lens set to a small aperture size. Simultaneously or near-simultaneously with capturing the image, the camera captures photogrammetric range data pertaining to depth of objects in a field of view of the camera, using the range sensor. The processor then processes the photographic image data using the photogrammetric range data to obtain second photographic data simulating an image captured using a lens set to an aperture size larger than the small aperture size.

1. A method, comprising:
capturing a photographic image data of a scene using a camera having a lens set to a first aperture size; concurrently with capturing the image, capturing photogrammetric range data pertaining to depth of objects in a field of view of the camera at least in part by using the lens in combination with a stacked sensor array configured to detect photogrammetric measurement light at two or more defined points in a light path from photographed object to an image sensor of stacked sensor array distal from the photographed object; and processing the photographic image data using the photogrammetric range data to obtain second photographic data simulating an image captured using a lens set to a second aperture size, wherein the second aperture size is wider than the first aperture size.
